Sign in with google+ and facebook login in sign page of bagisto ecommerce

Hi, can anyone tell me about sign in with google+ and facebook login in sign page of bagisto ecommerce, I have tried with google+ but I am getting like this (404 The Page you are looking for does not exist or have been moved. Navigate using sidemenu.), Please If you have source code then send it to me,Thank You.

config/app.php

I have added Laravel\Socialite\SocialiteServiceProvider::class, in providers and 'Socialite' => Laravel\Socialite\Facades\Socialite::class, in aliases

If anyone created sign in with google+ or facebook then please send me the source code.

Actually I have created redirectToProvider() method and handleProviderCallback() method in SessionController, is it correct or not, I don't know. And I have created routes in pakages/Webkul/Shop/src/Http/routes.php

Now sign in with google+ and facebook is working fine for me, but after successfully sign in with google+ also sign in button is showing below account drop down instead of logout button. Please refer below is the screen shot for this problem. can anyone give me the solution to sort out the issue, thank you.

In 'handleProviderCallback' method, when you got data from source(ex-google
) then you need to implement login functionality according to that data & you are missing this.
So, Kindly take pull from this repository - https://github.com/rahulshukla-webkul/bagisto-socialite.
We have implemented this one here.
